About Telnyx

Telnyx is an industry leader that's not just imagining the future of global connectivity—we're building it. From architecting and amplifying the reach of a private, global, multi-cloud IP network, to bringing hyperlocal edge technology right to your fingertips through intuitive APIs, we're shaping a new era of seamless interconnection between people, devices, and applications.

We're driven by a desire to transform and modernize what's antiquated, automate the manual, and solve real-world problems through innovative connectivity solutions. As a testament to our success, we're proud to stand as a financially stable and profitable company. Our robust profitability allows us not only to invest in pioneering technologies but also to foster an environment of continuous learning and growth for our team.

Our collective vision is a world where borderless connectivity fuels limitless innovation. By joining us, you can be part of laying the foundations for this interconnected future. We're currently seeking passionate individuals who are excited about the opportunity to contribute to an industry-shaping company while growing their own skills and careers.

Our backend team is building a highly-available and distributed data pipeline that powers Telnyx products like Voice, Messaging and Wireless. We leverage the Telnyx private backbone network to build a cloud-agnostic data platform that processes thousands of messages per second.

With our lean team, we're currently running and managing more than 30 dockerized microservices deployed in multiple regions in the U.S. and Europe. We are looking for a senior Java backend engineer with deep knowledge of Java Core.

In this role you will

Work on 30+ microservices implemented in Java 11 and Scala that process, aggregate and expose all data our telecommunication and messaging engines generate
Improve performance of our pipeline — we currently process 10k messages/sec and are growing
Architect our services and pipelines so they work with minimum latency in all our locations around the world (U.S., E.U., Australia, South America)
Implement fraud detection processes with machine learning (Kafka and Kafka Streams)
Deploy services to multi-cloud Kubernetes environments to achieve 99.999% uptime
Push code to production multiple times a day

What we're looking for

Degree in Computer Science, Information Technology, or equivalent work experience
4+ years of experience with Java and its ecosystem of tooling
Experience with at least one of these databases: Cassandra, ClickHouse, or OpenSearch
Experience with AI tooling, or a strong willingness to learn

Nice to have

Experience with Scala or another functional programming language
Experience with Linux, Git, and Docker in a CI environment
Experience with distributed systems and systems that maintain "five nines" (99.999%) of uptime
